Servicing & General Maintenance
✓
DO carefully remove any accumulated dust from the outer enclosure once a month.
NEVER spray lighter gas, paint or other aerosols near detectors or monitors.
NEVER paint the device. Paint will seal vents and may interfere with the device.
It is recommended that any detectors connected to the system are inspected and serviced
at least annually from the date of installation for optimum performance and protection.
Avoid exposure of high concentrations of alcohol found in many products, this can damage,
deteriorate or affect gas detectors. For more information refer to your detector manual.
